specification, reference'being had to the accompanying drawings.

h [y invention relates to the manufacture of artificial ice from raw water, and has more particularly to do with apparatus for manufacturing artificial ice according to the method described in my pending :rpplieation Serial No. 438,373, filed June 1 3, 1908.

The method of freezing referred to. generally speaking, consists in applying a freew ing medium to the'uppcr portion only of a suitable receptacle, thereby maintaining a non-freezing zone of water below the forming ice, and causing the water in the ro ceptaelc to circulate by introducing air thereiuto through or adjacent to such non-Frewr ing zone. h. the freezing period is best fillet-ted by introducing thereinto through the non-free lug zone compressed air \vh n ris' s throu eth the water, thereby causing; the water to circulate and maintaining the lighter impurities and air bubbles therein in a state of 1notion so that they do not. adhere to the fat of the forming mass oi. ice and. consequently are not frozen into the ire hlotic. The heavier impurities may settle down into the non-flexing); zone. where they remain until the freezing operation is t-oiuple'led.

In the accompanying drawings, illustrate two forms of apparatus by which the process referred to may he carried into ell'ect,-l igure l. is a longitudinal Vertical section. of a. form of apparatus designed .tor freezing according to what is known as the can system, the water to be frozen being contained in av can or receptacle of the shape of the block of ice to be formed. and practically the entire mass of water in the receptaele hein frozen to form the finished block; Fig. 2 is a erossseetion on line of Fig. 1 Fig. 25 is a vertical section on line --3 of Fig. 1: Fly. 4 is a vertical. section on line 4- of Fig. l; Fig. 5 is aperspective view of one 01. the damper plates or diapbragnis Which-control the dirmztion ol tlow of the brine; Fig. (3 is a partial longitudinal sectional View, showing an apparatus de- The circulation of the water dur- :l to he employed for freezing ice aeeording to whatv is known as the plate 5; stein. using in improved method; Fig. I a partial horizontal. se on on line 7-7 of Fig. 3; and Fi 8 is'a partial or section. on line 8-8 oi Fig. (5.

Referring first to the construction shown in Figs. 1 to 5, inclusire,6 indicates a tank or receptacle in which is placed the water to be frozen. As shown in. Fig. It, the extreme upper d oi said tank is of somewhat greater anieter and 1s fitted with a cover 7.

H2 is also provided with an overflow pipe 8, as shown in l. indicates a Well at the bottom of the tank (5 in which is provided a tube 10 having an .ir erted funnel or flaring portion 11 atits lower end into which projects an illjGCt-(JldlOZZlt-Z 12 connected to an air-pipe 13. The Well 9 is also provided with a drain-pipe 1% having a valve 15, as shown in Fig; l.

V Preferably the pipe 1t). tor-nozzle 12 and drain-pipe lat are all a detae ble cap or head lose my be readily removed. The pipe rably placed centrally in the well 1H centrally disposed rel" 'yely to the hottoni 17' of the tank. Thus it Will be seen that the water in the tank tills the well 9 and that by injecting air into the pipe 10 the Water in the Well may flow up between the nozzle l2 and the tunnel ll. being carried with the ineo 1g up into the tank. thereby t re-thing a current of water having); air iniern'lingled t'lu h which flows up through the tank and zgitates or circulates the wat r therei n. The violence of the movement. or the water depends upon the air pressure and ordinarily is sufficient to cause the water in the tank to maintain a pronounced circulation. The pipe 13 is supplied with compressed air from anysuitablc source of apply. The tank 6 is surrounded loy a icket 18. except at the extreme upper and lower portions thereof, and said jacket is provided at its upper end with an inlet pipe .Ill and at its lower end with an outlet; pipe 2:2. through which brine or other freezing fluid is caused to flow into and out of the jacket. and around the tank (S. The brine is cooled by any suitable refrigerating apparates, such as an ammonia compressor and coils. For the purpose of controlling the flow of brine around the tank 6 the-jacket 19 is provided with a series ot plates or dia phragnts 30 which are preferahlv the 1'0 I as indicated by the arrows in Fig. 1. It, w1ll,

J shapeshown in Fig. 5, being, in the construction shown, U-shaped so that they extend across one endand the two sides of the tank shown 1n Figs. 1' and 4, so that the brine admitted; through the' pipe 19 is compelled to flow to the opposite end of the ,tank 6 before it can pass down .to the nextst'ratum, flowing back and forth as it progresses downward,

be noted also that the lower portion of the posed. to atmos heric temperature "and is not tank 6 extends down a considerable distance below thelower portion of the jacket 18, as shown at 21 in the drawings. This down wardly-extending portion of the tank is exexposed to the rine, so that it constitutes the non-freezing zone of the can or tank, substantially no ice bein formed therein, the water in the bottomp the can bein always ina fluid condition. This portion-o 'the can also'forms a r 'wervoir' in which the solids separated from the freezin water, as well as the impurities. expelled; y the forming ice, gradually accumulate so that they remain separated fromv the ice and are-held in a state of nsion to a' greater or less extent by the water contained in the bottom of f the can. Furthermore, this unfrozen body. of water serves as a medium through which the air admitted to the 'water to e frozen is introduced without subjecting itv to a'freezin temperature, thus avoiding the da er ,of

ogging the air pipes by freezing 'of e moisture naturally contained in the air, as would be the case if the air pipe wereexposed to the cold brine, or werem contact with the water in the. can at a low temperature. By this means I also avoid freezin the air pipeinto the blockof ice, as woul any suitab be the result if the air pipe were extended into the freezingchamber, and in addition I avoid the use of. mechanical devices within the freezing tank or can, which is objectionable for the same and other practical reasons.

In Figs. 6, 7 and 8 I have shown an ap-- paratus designed to carry out my process in connection with the manufacture of ice according 'to' the plate system As therein shown, 22 'indicates a tank. of suitable dimansions and shape adapted to contain the 'water to be frozen. 23 indicatesa series of coils adapted to contain. ammonia, or other freezing agent, and supplied therewith from e source. In Fig. 8 I have shown said coils as being provided with ipes 24-25 through which the circulation 0 animonia, or other freezing agent, is maintainedi As best shown in Figs. 6 and 8, the coils 23 are placed transversely in the tank 22 and. are elevated a short distance above the floor thereof, being preferably supported Thus a zone of wateriis pr ovided in the tank which lies, be-

- ing it necessary to remove a lar g the m mg on the next ad acent 09$!) elther side,

in the manner shown in F ig. 6. For the purpose of maintaining the water in the tank in a state of circulation, air pipes 27 are provided in the non-freezing zone at the bottom of the tank, said pipes being provided-with transversely-extending perforated pipes 28, as shown in Fig. 7, through which the air may escape into the water 1n the tank. The

transverse pipes 28 are placed substantially centrally between adjacent coils 23, as shown in Fig. 6, so that the bubbles of air rise in planes about midway between the successive. coils, thus maintaining-a substantially uniform circulation throughout the tank.

Heretofore in making ice by the plate system it has been the practice to'ap 1yv the freezin' temperature to the full dept of the entire ody of water, the freezing plates or coils extending to the floor of the tank containing them, so that when frozen the mass of ice extended to the bottom of the tank, thus freezing in all the impurities and makpart of the ice at the bottom of each bloc to get rid of such impurities. By the use of my improved apparatus, however, I avoid this objection, thereby securing a considerable per cent. more of merchantable ice than it has been possible to secure by theuse of any prior apparatus of which I am aware.

So far as I am aware, I am the first in the art to provide for maintaining inthe water receptacle a body of unfrozen water in a zone below the forming ice and causing the water in the receptacle to circulate'by introducing air thereinto through the water in'or adjacent to such non-freezing zone,

and the claims hereinafter made are, therefore, to be construed accordingly.

That which I claim as m invention, and desire to secure by Letters atent, is, 1. An'ice-making apparatus, comprising a receptacle adapted to contain water, means for applying a freezing medium to the upper portion of said receptacle,'means for maintaining the lower portion thereof at a non-freezing temperature, thereby maintaininga non-freezing zone of water insaid receptacle below the forming ice,- and means for causing the water in said receptacle to circulate as freezing progresses.
